The activation and selective transformation of virtually inexhaustible or easy-to-generate
chemicals like N2, O2, CO2, CO, H2, or methane gas to value-added products is a lively …

Well-defined molecular systems for catalytic hydrogen production that are robust, easily
generated, and active under mild aqueous conditions remain underdeveloped. Nickel …

Quantum chemical approaches today are a powerful tool to study the properties and
reactivity of metalloenzymes. In the field of solar fuels research these involve predominantly …

Catalysis of H2 production and oxidation reactions is critical in renewable energy systems
based around H2 as a clean fuel, but the present reliance on platinum-based catalysts is not …

Despite extensive studies on [NiFe]-hydrogenases, the mechanism by which these enzymes
produce and activate H2 so efficiently remains unclear. A well-known EPR-active state …

Inspired by the natural [NiFe]‐H2ase, we designed mimic 1,(dppe) Ni (μ‐pdt)(μ‐Cl) Ru (CO)
2Cl to realize effective H2 evolution under photocatalytic conditions. However, a new …
